VACUUM DUST-nanowar..

To all whom 'it may concern:

Be it known that' we, CHARLES B. FOSTER and lViLMoT lV. GLIDDEN,citizens of the United States, residingat Oak Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Vacuum Dust-Removers, of which the following is a. full,clem-,and exact deoperator, regardless of thc angular position of thehandle with respect to the nozzle, and thereby maintain the dust inletin the proper relation with the object to be cleaned.

Another objectis to simplify the construction of devices of this type,and to avoid the necessity of providing packings and. the like vto'prevent leakage between the movable members of the nozzle.

Other objects and advantages will appear in the course of thisspecification and the essential features will be more particularlypointed out in the claims.

The invention is clearly illustrated in drawings furnished herewith inwhich- Figure l is a perspective view of a cleaner embodying ourinvention. Fig. 2 is an un`y der plan view. Fig. 3 is a side view withthc handle portion broken away. Fig. 4 is a cross section taken throughthe nozzle.- Fig. 5 is a perspective view of a fragment of a hood. Fig.(i is a vertical section taken on t-he line (3&6 Fig. 3. Fig. 7 is aplan view of a fragmentof the foot. Fig. 8 is a cross section on theline 8-8 Fig. 2. Fig. 9 is a plan view of a slightly modified form ofthe device, with n portion of the handle broken away. l0 is a sideviewthereof. Fig. l1 is a central vertical section of said modiedform, anzilig. 12 is a side-view of one of the members of the nozzle portion.

Referring first to Figs.- 1 to 8 inclusive of the drawings, A,represents-a handle that is arranged to be connected to a hose 10, which-leads to a suitable vacuum apparatus for Specication of Letters Patent.

producing the necessarysuction. The handle, A, is in the form of a tubeand has secured upn its lower end a nozzle B, which is moved back andforth along the carpet or rug in' the usual manner in cleaning the same.The nozzle is preferably constructed of two members 202l, theme1nberf20,' being tubular in form and fitting within the open lowerface of the member 21. The member 20, acts as a pressure foot andcontains a dust inlet upon its loweiyface, which dustinlet is in theform of a series of perforations 29., extending longitudinally of thepressure foot, and through which the dust 'enters the nozzle tened topresent a flat pressure tace for con-- tact with the object to becleaned. The upper side of the wall of the foot 20, is slottedlongitudinally as shown at 23, thus forming a direct passage waythroughthe foot 20, andI extending through the ent-ire length thereof.Shoes .24, are provided upon the ends of the foot Q0, which "shoespractically form continuations of the fiatlower face, the objectbeing togive to vthe nozzle a large base or bearing surfaceupon the carpet, sothat pressureupon the nozzle from above will always tend to hold thelperforated pressure face in close contact with the carpet.

rIhe hood Q1, incloses the slot in the upper side of the foot 20, andcontains two bearing faces 25 that ht snugly upon the eX- terior wallsof the foot 20. The hood `and foot portions are pivotally connectedtogether, as by lugs 2(1,wl1ich'project out from the end walls 27, ofthe foot portion, and ears Q8, that are secured to the hood. i 'Asshown, the ears '28 are in the form of plates, that are screwed to theend walls 29, of the hood. The pivot connection is provided merely toloosely connect the two parts together. As soon as suction is applied,the foot portion is drawn into firm contact `with the bearing faces Q5,of the hood, and the pivot;- connections tenjiporarily lose theirusefulness. A nipple 30 extends outV from the hood 2l A, forming theconnection between the handle and nozzle.

In the modified form, illustrated in Figs. 9 to l2 inclusive, Arepresents7 the tubular handle and B theinezzle, the pressure foot ofwhich is rotatably mounted with respect to said handle. The nozzlecontains two members 20, 21|', the' member 21'., secured upon the handleA', hyp/,means cfa and this lower side is Hab being lil) nipple 21a, androtatably connected to the member 530 by means. of a hood 2lb thatlpartially encircles the member 20. Said member; 20 acts as the pressuretoot and contains inlet perforations 322 through which the dust enters,andan outlet opening 23 provided which registers with the openmg inthenipple 21, thereby affording a direct assageway through the nozzle tothe han le. The member 21, contains a segmental bearing tace upon itslower side upon 'which the pressure foot is seated, and

-said member 2l', is held against longitudinal movement upon.t`nepressure foot by suitable means here shown as pins or screws 21C. thatpass through slots Qld formed in. the hood 2l". The hood 2lb, has asegmental bearing tace, somewhat more than a semicylinder in extent, andthe nozzle member 201, is cylindrical and lits in the concave face ofthe hood 2lb. rllhe cylindrical wall of the nozzle member 201, isiattened on its lower side to form the face which bears upon the objectto be cleaned, and also to facilitate the removal or replacement ot' themember E201, on the hood without the removal. of the shoes Q41. This isaccomplished by unscrewing the screws 200, and turning the member 201,until its flat side comes in front of either edge. of the hood,Awhereupon the member 201, may be removed laterally through the gap inthe hood Bearing shoes 24S, are secured upon the pressure i'oot, 20 toprovide means for preventing the tilting of the pressure foot, whichwould otherwise be occasioned on account ot the shifting ot the handl inthe use of the device upon the object to be cleaned.

ln operating the cleaner, suction is applied to the hose l0, and thecleaner is moved back and forth across the carpet, rug or other lilreobject to be cleaned, the flat bearing tace of the toot being held inclose conln moving the nozzle.

tact with the carpet. bach and forth, the hood is caused to` roclr orturn upon the foot portion, by reason of the .'act that the angularposition of the handle is constantly chan ing with respect to pressuretoot ando en the handle is swung down quite close to the floor, as forinstance when the nozzle is pushed under some article ot furniture. lnorder that the best results may be had, the flat bearing face should beheld in hrm Contact with the object that is being cleaned, inasmuch asthe suction then causes air nap of the carpet from both sides ot theperiorations before passing into the foot. 4ln this rn anner a morethorough cleaning of the object can be had because all of the suctionforce is utilized and practically none is lost. Furthermore, the nozzleis under control oft the operator and the pressure upon the carpet canbe maintained at his will. 'We are-thus enabled not only to remove thesurto pass throng the i i l evt/,eso

tace dust but practically all of the dust that has lodged in the body otthe carpet, This is practically impossible whore the nozzle travelslightly over the surface of the carpet or part or" the slot is uncoveredso that the air will rush directly into the nozzle withhout irst passingthrough the nap or body of the article to be cleaned. lt will beperfectly obvious that the pressure which the operator exerts inoperating the cleaner will ,at all times maintain the toot in an uprightposition upon the carpet, and that no particular care need be taken bythe operator to do this as the'tlat bearing tace will practicallyprevent the tilting or rocking of the toot.

We realize that various alterations and modifications of the device arepossible without departing from the spiritof our invention, and we donot therefore desire to limit ourselves to' the exact construction shownand described except as particularly pointed out in the claims appendedhereto.

We claim as new and desire to secure Letters Patent l.
